TYPEWRITING MACHINE.

Application filed March 14, 1923. Serial No. 624,889.

To all whom it may concern: I

Be it known that I, JEssE A. B. SMITH,

a citizen of the United States, residing in' Stamford, in the county ofFairfield and 6 State 'of Connecticut, have invented certain new anduseful Improvements in Typewriting Machines, of which the following is aspecification.

This invention relates to typewriting machines of the fan-fold orcontinuous billing type, such as is illustrated in the Wernery and SmithPatent No. 1,132,055, dated March 16, 1915.

For use in connection with a continuous billing machine, in practice, itis sometimes desirable to have similar forms printed on differentweights, colors and textures of paper. When this is done, it is obviousthat the advantage is lost which might have been derived from printingthe forms in repeated transverse rows on a single web, each rowcontaining the same number of forms as there are copies desired; thislost advantage being the positive registration of all parts of the formsat all times when superimposed -over one another, due to theirsuper-imposition being accomplished by longitudinally fan-folding theweb on the longitudinal lines dividing the forms.

The use of different weights and textures of paper for making thework-sheets of a pack, and the absence of connection between thework-sheets along their longitudinal edges, which is'present in thelongitudinally fan-folded pack, permits the work-sheets of a pack tocreep on one another or to be fed unequally around the platen, thusthrowing the forms out of registration.

One feature of this invention is the provision of means for initiallyregistering and subsequently re-registering the forms on the continuouswork-sheets of a pack at the conclusion of each typing operation thatcom pletes one of the forms, using the regular binding holes in themargins or edgesof the forms for that purpose, at the same time that thework-sheets are being gaged forsevering the leading forms therefrom.

Other features and advantages will here ina-fter appear.

In the accompanying drawings,

Figure l'is a front elevation of the platen and carriage of a continuousbilling machine, which shows my invention mounte on the left of thepaper-table.

to act as a pin 2 is a sectional view through the carriage of acontinuous billing machine, showing the platen displaced in the usualmanner, to allow the work-sheets to be straightened out forre-registration and gaging, and illustrates the manner of usingmyinvention to accomplish that re-registra- 1 igure 'tion.

Figure 3 is a perspective view of my reregistering device.

Figure 4 is a diagrammatic view of the leading edge portion of acontinuous worksheet, showing how it is divided into sections bearingforms that have binding holes in their left edges.

As is usual in a typewriting machine of the continuous billing type, aplaten 5 is mounted on a platen-shaft 6 which is journaled in aswing-frame 7 mounted in a movable carriage 8.. The usual feed-rolls 9and 10 co-operate with a rear paper-table 11 to guide work-sheetsunderneath and around the platen 5. mounted on the swing-frame 7 servesto support the work-sheets as they emerge from the machine. Mounted onthe rear of the carriage 8 is the forward end of a workpresenting frame13 over which the worksheets are led to the entry or feed side of theplaten.

Fastened near the center of the papertable 12, to move therewith, is agage-bar 14 which carries an adjustable form-measuring and pin-findinggage 15. The gage 15 has a long leg 16 against which the leading edgesof the work-sheets may be drawn, while in straightened position, to gagethem for severing the leading forms therefrom, and finder for aice-registering pin later to be described. The gage 15 may be fastenedin various positions on the gagebar 14 by a thumb-screw 17. Fastenednear A paper-table 12 I the side edge of the paper-table 12, to movetherewith, is a supporting bar 18' similar to the gage-bar 14.Adjustably mounted on the supporting bar 18 is a re-registeringpin-carrier device 19 having a long leg 20,

bent over near its end to form a projection d re-registering pin-carrier19 may be fastened in various positlons on the supporting bar gularly toafford a positioned that it will be in 18 by a thumb-screw 25-. Aweb-severing knife 26 is fastened as usual in the swingframe 7.

The bar 18 supporting the pin-carrier 19 and pin 22 is mounted on a sidegage bracket 35. One end of this bracket is bent anbase 36 to which thebar 18 may be attached. The bar 18 is held in fixed relation to thebracket by screws, rivets J or any other suitable fastening means,seated in the corresponding apertures 37 in the bar and bracket. Theopposite end of the bracket 35 has an enlarged portion or foot 38, onthe opposite ends of one edge of which are arranged angularly disposedfingers 39. These fingers aid in holding the supporting bracket 35 infixed operative relation to its supporting member, when the stud bolt 40or other fastening means is inserted into an aperture 41 provided forthat purpose, in the bracket foot 38. The bracket 35 itself is mountedupon a connecting bar 42 oining the opposite ends of the swing-frame 7,and is in the position usually occupied by the ordinary paper sideguide, the bracket 35 being in fact the usual side guide with its endlaterally bent to provide the supporting base 36. The bracket 35,although acting as a support for the'bar 18, also performs its usualfunction of guide to the side edges of the paper pack, and thus has adouble duty of side guide and support. By utilizing this bracket tocarry the bar 18 with its adjustable re-registering pin, this pin is soaccurate alignment with the perforations on the left marginal edge ofthe work-sheets, and will when adjusted properly function to effect there-registering of the work-sheets expeditiously.

In operation, a pack 27 made up of worksheets 28, 29 and 30 is fed intothe machine from the work-presenting frame 13. The work-sheets 28, 29and 30 have forms 31 printed thereon which have binding holes 32 and 33punched in one side near its margin or left edge, as shoWn in Figure 4.The worksheets 28, 29 and 30 may all be of different colors and texturesof paper and have no connection with one another.

It will he understood that the work-webs are interleaved with carbn-sheets in any usual and convenient manner. But since the work-webs areprovided with a series of perorations near one marginal edge thereof forreception of the re-registering pin, it is necessary to interleave thecarbon-sheets between the work-webs, so that the body of thecarbon-sheets will be to the right, of, or at least free from, theseperforations. This is necessary in order to keep the perforationsunobstructed and permit the reception of the re-registering pin thereinand thereby permit the oamming action of the conicalshaped portion ofthe pin.

Assuming that this is to be an initial typing operation, and that theleading edges of the work-sheets 28, 29v and 30 are all selvage edges offresh rolls of Worksl1eets, the leading edges are brought intoregistration and alignment and the platen lowered. The binding holes 32and 33 of the first forms 31 will also be brought into registration bythis operation and, of course, the forms 31 will be in alignment andregister with one another too. The operator now advances the pack 27until the first writing line of the first forms 31 is opposite theprinting point of the machine, when the typing operation is begun. Asthe typing operation progresses, V. the operator linespaces the pack 27until the matter is completely typed and the first forms 31 finished.The operator now releases the swing-frame 7 and lifts the platen 5 untilthe pack 27 can be straightened out and drawn forward. The leading edgesof the work-sheets 28, 29 and 30 will have been shifted out ofregistration a trifle by the creeping of the sheets resulting from theline-spacing operation, but this is disregarded until the leading edgeof the pack 27 gages the long leg 16 of the form-measuring andpin-finding gage 15. The operator holds the leading edge of the pack 27against the leg 16 with the first finger and thumb of one hand and runsthe thumb of the other hand along the edge of the pack 27 until theedges of the top binding holes 32 of the first forms 31 of theworksheets 28, 29 and 30' engage the conical surface 24 of there-registering pin 22. The fact that the gage 15 and the structure 19carrying the re-registering pin 22 are adjustable with relation to boththe cutting knife 26 and to eachother enabled the operator previously toso position the gage 15 and the carrying structure 19 with relation tothe various distances involved that, after the thumb has finished itsstroke and after the conical surface 24 of the re-registering pin 22 hascompleted its camming' action against the edges of the top binding holes32, the work-sheets 28, 29 and 30' will be firmly seated on thecylindrical portion 23 of the re-registering pin 22, with their leadingedges all in registration again againt the leg 16, and, of course, withthe forms 31 on all of the work-sheets also in registration with oneanother, as shown in Figure 2. The platen 5 is again swung to normalposition in engagement with the feed-rolls 9 and 10 and the first forms31 severed from the pack 27, after which the operation may be repeated.

Although the gage 15 and the carrier 19 with the re-registering pin 22'thereon are slidably adjustable on their respective supporting bars, andtherefore to each other and to the web-severing device, it is to beclearly understood that during the typing web-severing gage operationthe re-registering pin 22 and structure immediately carrying it isnormally in a stationar Y or locked relation to its supporting bar. Itis not used to draw the leading edges of the work-sheets to the gage 15.after the typing of each work-sheet form, but is set and locked inadjusted position and so remains until readjustment becomes necessarybecause of the change in size of the work-sheet form or the location ofperforations thereon. In this respect the function and operation of there-registering pin in the. present invention is in marked difference tothat in my Patent No. 1,304,213, dated May 20, 1919. The re-registeringpin device of that patent is specifically the means by which thework-sheets are drawn to the therein, and given their severing positionsafter the completion of the typing operation on each form. Thereregistering pin device of that patent is not locked, and no provisionis made for looking it. But after the movement of each form, followingthe typing operation, the reregistering pin device by gravity actionautomatically assumes its normal position at the base of its supportingor carrying arm, ready to effect another movement of the typed forms.

If the initial registration of the forms 31 is to be accomplished withWork-sheets from which the selvage edges have been torn, the leadingends of the Work-sheeets 28; 29 and '30 are brought into registration bycen tering the holes 32 of the leading forms 31 of those work-sheets onthe re-registering pin 22, while the sheets are straightened out. Thiswill bring the dividing line between the first and second of the forms31 at the severing knife 26. The platen 5 may then be lowered to itsnormal position and the first forms 31 severed from thework-sheets 28,29 and 30 and thrown away. operation may then be begun and be continuedas outlined above.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
